FEEDING MECHANISM FOR CUTTING-OFF MACHINES.

Specification of Letters Patent.

Application filed March 13, 1913.

Patented Der. 16.1913.

Serial No. 754,018.

To all 're/wm it may concern Be it known that I, MAX Maynas, a citi zenof the United States, residing in Phila delphia, Pennsylvania, haveinvented certain Improvements in Feeding Mechanism for Cutting-OftMachines, of which the following is a specification.

The object of my invention is to construct a device for accuratelyfeeding bars, or other shapes, to a cutting off or' other tool so thatafter the device is once set the bar can be cut off, for instance, insections of the same length. This object I attain in the followingmanner, reference being had to the accompanying drawings, in which:

Figure l is a side View illustrating my improvement and showing acutting ofl:1 tool in dot-ted lines; Fig. 2 is a plan View; Fig. 3 is atransverse sectional view on the line a-a, Fig. l; Fig. 4c is a sectionon the line ome, Fig. 2, and Figs. 5 and G are views of modifications ofcertain features of the invention.

Referring to the drawings, 1 is a part of the base of a cutting tool onwhich is the clamp 2 shown by dotted lines.

3 is the main framework of the cutting off tool.

Projecting from the base 1 is an I-beam l, in the present instance,which is supported by any suitable means at its outer end and secured toone side of the web of the I-beam is a rack 5.

6 is a carriage mounted on the I-loeam and having plates 7 whichunderlap the upper flange of the beam so as to hold the carriage in theproper'position. In order that the carriage may be readily adjusted onthe I- beam, I mount two rollers 23 on the carriage which rest directlyon the top of the I-beam so thatwhenthe hand wheel is turned, thecarriage can be readily shifted.

Adapted to bearings 8 on the carriage is a shaft 9 having a pinion 10,which meshes with the rack 5 and on the outer end of this shaft is ahand wheel 11 by which it is turned to traverse the carriage on the I-beam to and from the cutting tool.

Projecting upwardly from the carriage is a goose-neck 12 which has aclamping screw 13 and directly under the clamping screw is a V-shapedrecess 14 for the reception of the bar m to loe cut, said bar beingshown by dotted lines in Fig. 1. Projecting upwardly from the V-shapedgroove is a stop pin 15, which bears against the end of the bar Thegoosemcck is detaehably 1nounted on the carriage and has a T-headadapted to slide in the carriage.

1G is a head arranged to be clamped to the upper' flange of the I-bcam.Said head has plates 17 which undcrlap the upper flange of the beam andmounted in a bearing on one of the plates is a shaft 1S on which is a.cam 19 having a face beveled to engage the under portion of the flangeof the beam.

1S is a handle secured to the shaft so that, on turning the handle, the,head 1G can be clamped to the beam or released therefrom.

20 is a rod attached to the head 1G and this rod extends through anopening in the carriage G and has an adjustable collar 21 at its outerend, which can be locked to the rod by a handled set screw QQ. The rodis preferably graduated, as shown in Fig. l, so that the collar can bemore readily set in the proper position.

The operation is as follows l`he bar a: to be cut in given lengths ismounted in the V-slot in the carriage and is held by the clamp screw, asshown in Fig. 1. lf it be desired to cut the bar in one foot lengths,then the end of the bar placed in position at the cutting off tool whilethe carriage is located directly under the opposite end of the loar withthe pin 15 resting against the said end. The collar 21 on the rod isthen loosened and the head 1G adjusted so as to come in contact with theforward end of the carriage. The distance between the rear end of thecarriage and the forward end of collar should be twelve inches and thecollar is adjusted to this point after which it is securely fastened tothe rod. Then the head 1G is moved on the I-beam until the collarstrikes the end of the carriage, after which the head is fastened to theLheam and the carriage, with the loar to be cut off, is moved forwarduntil the end of the carriage comes in contact with the head. Thecutting off tool is then set in motion, cutting off the bar one footfrom the end. lVhile this cutting oft' tool is operating, the head isunclamped from the beam and is again moved forward until the collarcomes in contact with the rear of the carriage, when it is fastened,and, as soon as the bar is cut off, the carriage is moved forward untilit comes in Contact with the head and another foot of the bar willproject beyond the cutting ofi tool. By this means the entire bar can becut in one foot lengths, or in any lengths desired. Jfitter the carriagehas been moved up and the bar is in position to be cut ofi, it is heldon the main frame by the clamp 2, as shown in dotted lines; Fig. l.

In place of the clamping cam shown in F ig. 4, the bolts which hold theplate 17il to the head 16EL may be made adjustable to clamp the head tothe beam, as shown in F ig. 5.

Two or more rods, as illustrated in Fig. 6, may be used instead of theI-beam and intermediate gearing may be used between the pinion and theshaft 9, as shown in said figure.

claim:

l. The combination in a feeding device for cutting off or other tools7of a beam; a carriage longitudinally adjustable on the beam; a clamp onthe carriage by which the bar to be Lout is secured thereto; a headadjustable longitudinally on the beam; a rod projecting from the headand extending through the carriage; and an adjustable co1- lar on therod.

2. The combination in a feeding devicer for cutting oii or other tools,of a base; a beam projecting from the base; a carriage mounted on thebeam; means for adjusting.`

the carriage; a Clamp on the carriage by which the-bar to be cut issecured to the carriage; a head located on the beamin advance of thecarriage; a rod mounted in the head and extending rearwardly through thecarriage, said bar being graduated; and an adjustable collar on thatportion of the rod projecting to the rear of the carriage.

3. The combination in a feeding device for cutting oiln and other tools,of a beam having a iiange at its upper end; a rack on the beam; acarriage adapted to slide on the flange in the beam; a shaft on thecarriage having a pinion meshing with the rack and a hand wheel by whichit is turned; a detachable clamp mounted on the Carriage for securingthe bar to be cut thereto; a head adj ustably mounted on the beam inadvance of the carriage; a rod extending rearwardly from the headthrough an opening in the Carriage; an adjustable collar on the outerend of the rod beyond the carriage, said carriage having `-sliapedgroove to receive the bar to be cut; and a stop pin projecting from theV-shaped groove against which the end of the bar rests.

ln testimony whereof; I have signed my name to this specifi-cation, inthe presenceor" two subscribing witnesses.
